Founded and led by physician-executive Mayank Gandhi and backed by Korean antibody specialist ABL Bio, NEOK launched from stealth in November 2025 with a $75 million Series A. Its dual-targeting approach binds two complementary tumor antigens at once, aiming to widen the therapeutic window and overcome the resistance and toxicity limits of conventional single-target ADCs. The company's two lead programs, NEOK001 (ROR1/B7-H3) and NEOK002 (EGFR/MUC1), both cleared FDA IND review in early 2026 and are headed into Phase 1 studies.
CatenaBio
CatenaBio is a UC Berkeley spinout building a next-generation bioconjugation platform for targeted cancer therapies. Its proprietary CysTyr platform uses an engineered enzyme, Catenase, to forge a site-specific bond between cysteine and tyrosine residues (the C-Y Bond) using only native amino acids. This lets the company attach multiple different drug payloads to a single antibody, producing Multi-Payload Conjugates (MPCs) designed to overcome tumor resistance where conventional single-payload ADCs fall short.
Fortitude Biomedicines
Fortitude Biomedicines is a Waltham, Massachusetts biotech that launched in early 2026 with $13M in seed financing to develop next-generation antibody-based therapies for autoimmune diseases and cancer. Its proprietary GLUE-DAC platform bolts molecular glue degraders onto antibody-drug conjugates, aiming to use catalytic targeted protein degradation to widen the therapeutic window of ADCs and overcome the resistance that has dogged the field. Its lead program, FORT-202, is a first-in-class T-cell targeting bispecific antibody for axial spondyloarthritis expected to reach the clinic in the first half of 2027.
